Hurry please. Doug is interested in testing the effectiveness of a new ringworm medication
for cats, so he divided some cats with ringworm into two groups, group X and
group Y, giving the medication to group X, but not to group Y. Group Y is the
control group.
True or False

True

Step-by-step explanation:

Control groups in experiments ar egroups that are separated from the others involved in which the independent variable being tested cannot influence the results. Control groups can also be separated into two groups which consist of positive nad negative.

Hope this Helps!

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
